INTERLOCI-KING HECHANISM FOR VISIBLE DISPENSING- APPARATUS.

Such apparatus has a valve controlling the flowv of the liquid to the service pipe and another valve controlling the flow of unused liquid through the overflow or any other pi e to the source of supply.

he principal object of vthe invention is to prevent both these valves being open at the same time. Then the operator has the servev valve open dispensing gasolene to a. customer the drain-back valve must be kept closed or art of the gasolenein the container, Whlch the customer is entitled to receive, may be .drained back to the storage tank, cheating the customer. If the serve valve could b e o ened when the drain-back valve is open` t e pump owner could be cheated.

'In the articular embodiment of my invention se ected for illustration,

Figure 1 is a vertical axial section on the line 1--2-1-2 of` Fig. 3 through the visible container (broken through horizontally for shortening), the container support and valve nest andthe top of the edestal; both` the serve valve and the drainack valve being closed and the interlocking bolt in such position that the serve valve maybe opened but the drainback valve cannot bel opened.V

Fig. 2 is a similar view, the upper parts ofthe container being broken away, the drain-back valve'bein open and locked, and

e in closed position by v Fig. 3 is a horizontal section on the line of Fig, 2..

Fig. 4, a detaiLofrthe valve mechanism only, is an elevation from-the drain .back

Fig. 5 is a vcross/section (in the line 5 5v ofF1'.,4."

Refrring now to the drawings, A is the, pedestal of a visible liquid dispensing appawith peripheral ange almdapted -to rest on `the top of the pedestal A. i Y -The visible`container B rests, on a base C,

` The drain backa'valve I is provided with a 1924.` serial No. rareza.

to the base C by bolts c3 and assists in housing and protecting the valves.

A preferably ornamental casing D forms the main part of the housing `for the valves andis preferably made in sections held together by screw bolts d, and-is readily removable without disassembling the apparatus. i Y The container has a top I). Within the container B, fill-pipe E terminates at a suitableheight and through it from its connection ,e the liquid'to be served is forced in any suitable manner, as by air, controlled by valve K. Also within the container B, terminates an overflow pipe F to carry the source of supply (not shown) excess liquid to the highest serving level.

A oat 4meter G of any suitable form mav be provided.

- The liquid to be served passes through the cylindrical boss c1, then through an L shaped itting on the serve valve H, then through said valve H., then through an L shaped pipe h1 to which the serve hosel (not shown) is threaded. v

The unused liquid in the containenB is drained back to the source of supply (not shown), flowing through the passa c* in the base C, then through an L Ashap fitting on the drain back valve I, then throng said valve I, then through the post portion of a T whose crossbar forms the part F1 of.' the pipe F. i

The serve valve H is provided with a lever h with a flattened arm h integral therewith, with a hole It* therethrough. Com tiguous to said arm h is a bracket z integral with the L shaped littingh Yand has a hole h adapted to register with the hole h* l when the valve His closed.

With the position of the bar J shown in Figs. 2 and 5, the valve I may be opened an locked in open position by means of the push-bolt lock is as shown; and when the ar J is in the drain-back position the valve H cannot be opened.

In the positlon of the bar J shown in Fig. l, the valve H may be opened to serve liquid to a customer, While drain-back valve I cannot be opened. Said bar J may be shifted axially by pressing on the end that protrudes through a lever arm IIts movement may be limited by collars j. y

I claim as my invention and desire to se1 of the United States Y l. In a liquid dispensing apparatus having an elevated liquid container, a service outlet. a conduit to conveyliquid from said container to said service outlet, avalve in said conduit, a drain conduit, a conduit to convey unused liquid from said container to said drain' conduit, a valve for said last named connecting conduit, a valve lever for each of said valves, an arm on each of saidneva/soo valve levers, a fixed bracket contiguous to and on the inside of each of said arms, holes through said brackets and arms ada ted to align with each other, and an inter ockin bar adapted to pass through all of sai holes when in alignment but of such length as to pass through one only of said arms at a time.
